The variance inflation factors
WebAs you can see, three of the variance inflation factors — 8.42, 5.33, and 4.41 — are fairly large. The VIF for the predictor Weight, for example, tells us that the variance of the estimated coefficient of Weight is inflated by a factor … Consider the following linear model with k independent variables: Y = β0 + β1 X1 + β2 X 2 + ... + βk Xk + ε. The standard error of the estimate of βj is the square root of the j + 1 diagonal element of s (X′X) , where s is the root mean squared error (RMSE) (note that RMSE is a consistent estimator of the true variance of the error term, ); X is the regression design matrix — a matrix such that Xi, j+1 is th…
